Original application November 14, 1934, Serial No. 752,971. Divided and this application October 18, 1935, Serial No. 45,621

is anims.

The invention relates to rolls of partially severed paper and an improved method of forming the rolls, this application being a division oi my co-pending application, Serial No. 752,971, -led November 14, 1934. More particularly, the invention relates to rolls of relatively long and narrow strips of paper partially severed at a plurality of longitudinally spaced transverse lines, the lines of cut having a length less than the width of the strip whereby the several portions are connected by narrow marginal ties.

An elongated strip of thin, easily torn paper of the quality in general use for toilet paper cannot be wound into a compact roll after it is partially severed as described for the reason that the tension necessarily exerted on the paper to wind it compactly is sucient to completely sever the paper at the lines of transverse cut and the invention contemplates a novel method of slitting a blank sheet of paper, winding it into a compact multiple roll, and then severing the roll transversely at planes such that the individual rolls so formed are partially severed transversely by the slits previously formed in the blank sheet.

It is one of the objects oi the invention to provide individual rolls of paper comprising longitudinal sections or" practical length connected, at one marginal edge, by ties which are adapted to be severed by the slight pull normally necessary to unwind the roll.

1t is another object of the invention to provide a novel method of wrapping and forming a multiple roll oi paper from a single sheet, slit transversely in such a manner that upon cutting the roll at selected sections to form individual rolls, said individual rolls will each comprise a relatively narrow strip of paper partially severed along longitudinally spaced-apart transverse lines in such a manner that the strip comprises 40 a plurality of longitudinally extending sections connected by narrow marginal ties with the nem adjacent sections.

Still another object of the invention is the provision of a novel method of slitting, wrapping, 45 and forming a relatively wide sheet of paper into a plurality of individual compact rolls, each comprising a narrow strip of paper having the same length as the blank and completely severed transversely other than by narrow ties at a plurality of longitudinally spaced transverse lines.

Another object of the invention is the provision of a novel method of producing a compact roll comprising a narrow sheet of soft, easily torn paper divided into a plurality of longitudinal (Cl. M11-17) sections each connected to the adjacent sections by a narrow tie.

A. still further object of the invention is the provision of a novel method of forming toilet paper rolls which results in economy both in the 5 production and use of the rolls.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel method herein described and also in the construction, arrangement and combination of parts herein described and shown and more particularly pointed out in the claims.

Referring now more particularly to the draw ings, the numeral i0 designates Aa partially unwound multiple roll formed from a sheet of paper ll. The sheet II, preliminary to winding it into multiple rolls, is provided with a plurality of transversely extending slits I2 formed in any suitable manner such as by a die cutter or the like. 'Ihe slits I2 are arranged in longitudinally extending rows separated by common imaginary rectilinear parallel boundary lines indicated by 50 dotted lines I3 with the outer edges of each of the border rows of slits bounded by imaginary lines, indicated by dotted lines I4, preferably parallel to the lines I3, and closely spaced to the adjacent marginal edges of the sheet.

The slits I2, comprising each row, are staggered relative to the slits comprising adjacent rows with alternate ones of the slits comprising each row terminating in the same boundary line and the remaining slits terminating in the other boundary line of the row.

A sheet of thin, easily torn paper such as toilet paper having its slits arranged as described, provides suicient tensile strength to permit it to be wound into a compact multiple roll without tearing.

-The multiple roll I0 is formed from the sheet II by winding it closely about a relatively rigid tubular paper core I5 which serves as a mandrel and results in the completed roll being compact and substantially unyielding when subjected to transverse pressure. The multiple roll is then enclosed, as shown in Fig. 4, with a close fitting continuous wrapper 24 having marker lines 25 on its outer surface so spaced as to respectively overlie the longitudinal lines I3 and I 4 forming the boundary lines of the rows of slits I2. Any suitable indicia, such as a trade-mark or tradename or manufacturers name, generally designated by the letter K, may be provided on the wrapper 24 between the lines 25. The wrapper lines 25 indicate the sections at which the multiple roll should be cut transversely to provide individual rolls comprising strips of paper of the usual width.

Obviously the cutting of the multiple roll, at,

the sections designated by the lines 25, will sever the sheet II along the longitudinal lines IT and I4 and will thereby cut across and open each of the slits I2 at one end.

A compact roll of soft paper is liable to be distorted in the immediate area surrounding the cutting edge of the knife with the result that the lines of cut in the sheet II are more or less sinuous and may, therefore, not coincide exactly with the boundary lines but will curve away from and not intersect the ends of all of the slits. The tubular core I5 prevents such possible distortion and insures the cutting of the sheet in straight longitudinal lines.

The longitudinal strips, formed from the sheet II by the described cutting of the multiple roll along true rectilinear lines, each consists of a plurality of short sections connected with the adjacent sections at the lines of slit I2 only by a tie having a width equal to the difference between the length of the slits and the width of the individual rolls. Each individual roll thus consists of a section of the member I5 forming a core and a narrow strip of paper closely wrapped about the core but severed transversely leaving narrow marginal ties at a plurality of points. The ties occur alternately in opposite margins of the strip and have insufiicient tensile strength to permit the strip to be wound into a roll.

Fig. 2 illustrates another embodiment of the invention as comprising a multiple roll I 6 formed from a sheet of paper I1 wrapped about a core I5 and having transversely extending slits I2 arranged in a plurality of longitudinally extending rows bounded by imaginary lines I3 and I4. The slits comprising each longitudinal row are staggered relative to the slits comprising the next adjacent rows and are also shorter than the spacing of the adjacent boundary lines indicated by dotted lines I3 and Il. Alternate ones of the slits I2 in each row terminate in opposite boundary lines of the row leaving an unsevered portion adjacent each slit in which is formed a row of apertures I8 in alignment with and providing extension of each slit permitting easy severance of the sections and insuring that the sections will tear along the line of apertures. The multiple roll i6 is formed by wrapping the sheet il, slitted and apertured as described and shown, about a core l5. It is then covered with a wrapper 24 and cut transversely along the lines 25 which are arranged in the same planes as the boundary lines i3 and Ill.

Still another embodiment or' the invention is shown in Fig. 3 as comprising a multiple roll 2i) formed from a sheet 2i and wrapped about a core I 5. The sheet 2l is also provided with a plurality of transversely extending slits I2, arranged in longitdulnal rows but with the slits in each row l all terminating in the same boundary line and staggered relative to the slits in the adjacent rows. The longitudinal rows of slits, except one 'border row and the next adjoining row, are each separated irom the next adjacent row by an imaginary rectilinear line, indicated by dotted line 23 in which said border row and next adjacent row of slits both terminate. The outer ends oi the slits comprising the border rows terminate short of the edges of the sheet 2l and have their other ends respectively terminating in the outer line 22 and the line 23. The roll 2U is enclosed with a wrapper 22 in the same manner and for the same purposes as described for the rolls Il and I6, it being understood that the ends of the wrap- .-1 per coincide with the marginal edges of the sheet, and that the lines 25 respectively overlie the lines 22 and 23 and that by severing the roll at the lines 25, the sheet 2l will be cut along the lines 22 and 23.

The multiple rolls ill, I6 and 2D may be cut transversely as described by using any suitable tool but because of the soft and yielding qualities of the paper generally used in such rolls, the cutting is most satisfactorily accomplished by positioning the rolls in a close tting container whereby they are held firmly on both sides of the cutting section.

A typical device adapted for cutting such rolls is shown in Fig. 6 as'having a plurality of thin cutting discs 29 xedly mounted on a shaft 28 in spaced relation corresponding to the spacing of the lines 25 on the wrapper sheets 25. A container for-the roll to be cut is shown as comprising a plurality of axially aligned cylindrical members 3l fixedly mounted on a member 30. The member 30 carrying the members 3| is adapted to be moved towards and away from the shaft 28 by any suitable means such as a rack, not shown. The shaft 28 is adapted to be rotated by any suitable means with the discs 29 in operative engagement with the roll positioned in the members 3|, the spacing of the members being such as to permit entrance of and to maintain the discs in exact position. The multiple roll is 6 thereby severed by the discs 29 into a plurality of individual rolls having smooth ends and similar wrappers. The core I5 prevents any possibility of distortion of the inner portion of the roll by cutting and insures that the individual rolls will be bounded by smooth plane surfaces intersecting the adjacent ends of the slits provided in the sheets as a preliminary to forming a multiple roll.

Fig. 5 illustrates a typical individual roll. formed from the sheet II by severing the roll 20, as it appears with the wrapper section 24 removed and the roll partially unwound. An individual roll, formed from a sheet I1 as shown in Fig. 2, will be similar to that shown in Fig. 5 75 desde except that the ties will contain periorations in alignment with the slit portion. An individual roll formed from the sheet 2| will also be similar to that shown in Fig. 5 except that the tie will all be in the same margin. I

Thus it will be seen that I have provided compact rolls of toilet paper or the like substantially severed transversely at a plurality of lines to promote economy in use, the severance being sumciently complete that the roll could not be formed from narrow strips previously so severed and that I have also provided a novel method of forming such rolls with close tting'wrappers.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
